This study examined certain reported maintenance factors to better understand how they influence the accomplishment of shipboard maintenance in cruisers and guided missile destroyers. The data was generated by the Equipment Maintenance and Related Maintenance (EMRM) Project, Pacific, and other reports normally submitted by the ships. Though part of the data was broken down to work center level, this research did not go below the ship level. This study showed 1) how the accomplishment of preventive maintenance varied as additional maintenance requirements were scheduled; 2) how the accomplishment of preventive versus corrective maintenance changed as funds for repair parts were increased; and 3) how the ships' employment schedules affected their accomplishment of shipboard maintenance. Additionally, an hypothesis test was used to show that there was a difference in the maintenance activity of the EMRM test group ships compared to the EMRM control group ships.
